摘要： A method for estimating a channel from received signals transmitted via the channel, includes the steps of receiving the received signals with receiving sensors of a receiving device. The received signals are composed of a plurality of subscriber signals. The subscriber signals are marked with transmitter-specific fine structures. A subscriber signal of the plurality of subscriber signals is transmitted by a plurality of wave elements having differing incidence directions at a receiving point. An incidence direction of at least one of the wave elements is obtained in the receiving device. Directionally selective channel impulse responses are determined from the plurality of received signals and the incidence direction of the at least one wave element.

摘要： Signals distorted by multipath propagation are reconstructed. In a first step, the incidence direction of the wavefronts, that is to say of the respective d dominant signal components, is estimated and the signal components are reconstructed. The wavefronts are separated as a result of the first step. A second step reconstructs the signals distorted by multipath propagation with the aid of the wavefronts, separated by spatial direction, and therefore with the aid of the reconstructed signal components, through combination of the signal components, by assigning the determined d dominant signal components to the l associated signal sources and, expediently, determining delay times and weighting factors with a view to optimal combination of the signal components in order to reconstruct the signals. The method may be applied either to one-dimensional or two-dimensional evaluation of the incidence direction of the wavefronts, and is suitable, in particular, for mobile-radio or wireless communication systems, high-resolution radar image processing systems and sonar systems.

摘要： A radio communications receiver which detects radio signals and recovers data representative of the radio signals in a presence of contemporaneously detected interfering signals, the radio communications receiver having a detector that detects said radio signals and generates digital base band signals representative of the radio signals, a matrix former that forms a correlation matrix having rows and columns from the base band signals, and a data processor that generates a factor matrix of the correlation matrix, the factor matrix having rows and columns, and recovers data from the factor matrix. The data processor generates the factor matrix by calculating first elements of the factor matrix from the correlation matrix using a factorization algorithm in accordance with a pre-determined structure of the factor matrix, and forming second elements of the factor matrix by selectively copying first elements in accordance with the pre-determined structure.
